The prime objective is to utilise existing expertise in this field to produce a suite of programs that are user-friendly, have a short learning curve, yet deliver comprehensive in-depth engineering know-how and results to engine designers.

PRODUCTS
This product is a software package for the design, and design for manufacture, of components within or attached to the cylinder heads of four-stroke engines.
